If Lenovo has unintentional binaries slipping in the production image, the problems are way more serious than sloppy QA. How can I trust their peripheral chips and firmware? Or BIOS and SMM for that matter? Maybe some nasty things unintentionally slipped in their SMM code as well? https://en.wikipedia.org/wiki/System_Management_Mode https://en.wikipedia.org/wiki/System_Management_Mode There's no way I could verify all the firmware code contained in the laptop. Heck, not even one chip. Lenovo has had things not intended happening with their BIOS [1] as well. It's fixed now, but what else there might be lurking under covers?
